I bought this thing new in 1974 as a boot gun when I was working for the Border Patrol in Miami and it looks like it, but that's beside the point.
Overall, I probably haven't put 500 rounds through it.
There's some discussion and commentary about this little piece on this site and others that we needn't repeat. Overall, I think it's a pretty good little pistol, of its type.
Flaw: Keep in mind it is a Browning design; it assembles approximately like a Gov't Model, with a barrel link held in place by the cross-pin of the slide lock.
Here's the problem: the slide lock pin is being bent to the rear by the barrel link. I'm no gunsmith, but it seems pretty clear to me that the link is what's bringing the rearward travel of the barrel to a stop by yanking hard on the slide lock pin just before the barrel bottoms out. Something is out of spec, apparently.
This is one of the few cases I know of where a gun has apparently solved its own problem; the bending has reached a stopping point. That's effective but it's just not elegant! Once upon a time I straightened it but it just did it again in a few rounds, so I quite messing with it. Any gunsmiths out there with a thought?
Now, for parts: I need a hammer pin. The original pin is a pretty cheesy construction, I must say. It is hollow and the safety detent spring and pin fit inside it. The pin extends through both sides of the frame and, to keep it from slipping clear through and out the right side, it has (had, now) a flange on the left end of the pin. That flange was apparently pressed and perhaps glued on, but it was not machined as a piece with the pin itself. Reason I know all that is because the flange has come off and the pin worked its way partly out the right side during a string of fire. The flange was held in place by the shield of the safety, so I recovered it when I disassembled the pistol.
Is there anyone out there who knows of a parts source for this thing? Not Bob's Gun Store of backwoods Arkansas. Near as I can tell, he doesn't answer email or faxes and he may not have a talking telephone, 'cause there's no number I can find.
